IMPROVEM ENT IN GAS-RETO RTS.

Specification forming part of Letters Patent No. 200,820, dated March 5, 1878; application filed hereby declare that the followingis 'a full,

clear, and exact description of the same, reference being had to the accompanying drawings,.wher Y g l ,Figure 1 is a sectional view of my inven-' tion, showing one of the retorts as constructed perpendicularly to the other. Fig. 2 is another sectional "view, wherein the retorts' are placed parallel to each other.

Similar letters of reference indicate corre- A is a retortrfor wood orcoal, which, in

generating gas, is subjected to heat in theordinary'manner. -B is another retort for the reception of the gas generated in first one,

and communicating directly therewith at the back, as shown.

A series'of. tubes or bars, E, are placed in retort B, in order to increase the heating-surface thereof and 'prevent the .escape of any essential oils arising from the generation of the gases from either coal, wood, or oil, thus obtaining all the gases which can be generated from the substancesiused, the vapors generated in retort A having to pass in the irection of the arrows through retort B,'.

and coming in contact with the tubes or April 18, 1877.

bars placed therein before finding an outlet at the mouth of retort B, and thus becoming wholly decomposed. By this -means a greater quantity of gas is produced, and the formation of tar, which contains the better qualities of the substances used, is prevented.

O is a separateretort, for supplying oil-vapor to the retort A. This retort, being inclosed in the brick-work which surrounds the retort A, subjects the oil to a sufficient degree of heat to'vaporize it before it enters the retort A near the mouth, and comes in contact with the excessively-heated surface thereof, thus avoiding the deposition of carbon in any of the subsequent receivers of the gas.

I am aware that the use of two connectingcylinders in a gas-retort, one of which has fied.
